Why Do Men Lose Weight Faster Than Women?

As a woman trying to lose weight, you may have noticed that your male counterparts seem to lose weight far more quickly. The reasons for the ease with which men often seem to lose weight lie primarily in their size, their metabolisms and their hormone balance.

Exercise

  • Men and women have different body composition. On average, the male metabolism is five to10 percent than the metabolism of a similarly sized female. Men tend to have more muscle mass than women, which burns more calories than fat deposits burn.
  • Size does matter. The taller and larger you are, the higher your basal metabolism is. Men are generally taller than their female counterparts.
  • It is natural women to have more body fat than men. The healthy range of body fat for men is between 12 to 20 percent. For women, the range is 16 to 30 percent body fat. So a man of a comparable age has a head start to begin with because he tends to have more muscles and less body fat.
  • The primary male sex hormone, testosterone, burns more calories and body fat. Than the primary female sex hormone, estrogen. Estrogen is designed to support pregnancy and breast feeding by storing more body fat for emergency reserves. Women are born predisposed with a natural tendency to put on more weight than men.
  • Hormonal imbalances are more common in women than men. They go through different biological stages starting from puberty to menopause where they serve and nourish different hormonal needs of the body.
  • A study by the American Journal of Physiology revealed that exercising women burn 37 percent less energy than men. Women are smaller and have less lung capacity than men, so their workout capacity is less than that of men.
